To all lwlw/m 72mg/ comme@ 133e it known that l, FIANK l). Keener, a

Citizen of the llni'ted States, and residing at Amityville, L. L? in the county of Suffolk and tritate of llevv York, have invented eertain new and useful ln/iprovenients in Elea trie lliveting Apparatus, of which the followingy is a specification, such as will enable ,those skilled iii-the art to which it'apper-- tains to make and use the saine.

This invention. relates toriveting` appa ratns and particularly to electric rivetlng apparatus, andthe object thereof is to prothe crank shaft or other parts' of the apparatus; a further object being' to provide en apparatus of the class specified with a vertieally adjustable table or bed-plate on which the Work piece or Work piece holder is placed and which Will also aid in aecomplishing the object above set out. .v

The invention described and claimed herein is an improvement on that described and claimed in U. S. Letters Patent granted to ine May 1l, 1915, No. 1,139,300, and is fully disclosed in the following; specification, of which thel accompanying dra-Wing forms a part, in Whieh the separate parts of my irnprovement are designated bv suitable referenee characters in each oit' the views, and in which Figure l is :i side view of an apparatusv involving my invention;

Renewed l wardly directed top portion .fr-3, and comgfissng side members e* and transverse top iframe nienlhers o2 a und al hut my invention is not limited to any struction of the main frame.

vi V' i Y et] i-t reantei. i. rientro;` ie io. om portion *t oi the inem :Uranio is a Work supportiin J table o having a bottoni -openwork body portion i2 and this table in my nnprovementis made vertically edpistzihle.

The table Z1 connected with the side por# 7 tions of the main frame by a tonguev and groove Construction as shown at Zi'nn Fig.'

il, and vissed through oneI of the side flanges 'thereo are set screws 5* which operate in connection with a corresponding part of the point of adjustment y The table o is made vertically adjustable b v means o avertieelly arranged shaft c which has a bearing in ythe bottom `body portion of said table and 'in the base a2 'of the main frame, end the upper endportion of said shaif gear and 11min freine to hold the table at any desired inoiznted at right angles to said shaft is a supplen'iental' sheft o3' providedwith a pinion o4 which meshes with the gear c2l and at its outer end with a hand Wheel 05. The lower end or' the shaft o is serevvethreaded and passes through a correspondingly threaded bushing o mounted in the base a2 i of the main frame and by means of this' construction the table may he raised or lowered end held at any desired point of adjustment, whenever desiredu n Mounted `in "the central beekk portion of the mein traine and above the tahle "o is a i 1 n l inem ora-nir 'snort of, and mounted in the.

front top portion ot' the main freine is a is'lield in position by 'vertical strips et se` cured to the top portion of the main frame,

and in the bottoni portion ofthe plunger carriage is a curved spare or Chamber 'e3` partieu lar` con provided: with a beveled vertically inovelole plunger carriage o which ranged tubular head g3 through which the plunger f passes and vertically movable. and the head g3 is provided with laterally directed keepers y* in which is mounted a vertically arranged electrode support 71 which is cylindrical in form :nld brovided at its lower end with an enlarged head /F with which the yelectrode i is connected. as clearly shown in Fig. T. and as indicated in Fig. 3.

The electrode support z. is provided with a vertical slot at 713 through which is passed an arm 1'? pivotedto the central portion of the partI g at is and provided at its outer end with a handle and the inner end of said arm is'provided with a weight which normally holds the outer end of said arm and the electrode support z in their highest position.

The top of the electrode carrier and plunger guide g is provided with a hacliwardly directed extension y to the bottom of which is secured a transverse block or plate j and beneath the rear end portion of the part g5 is a transverse shaft. provided at one end with a backwardly directed arm k2 with which. is connected a rod -3 which is connected at t with a treadle in the bottom of the frame. and mounted on the shaft l.: is a clamp block k6 of the usual form and which operates inconnection with the block or plate j. as hereinafter described. and mounted in the sides-r1* of the main frame are stop screws 'T which operate in connection wit-h the part Q of the electrode carrier and plunger `uide g to limit the horizontal rotary movement of said part in the operation of the machine as hereinafter described.

Mounted in the top portion of the main frame on a. transverse shaft m is a rock beam m2 which is secured to said sha t't and provided aty its front end with a head m3 which tits in and operates in a corresponding aperture e in the vertically movable carriage e. The head m is provided in the bottom thereof with a transverse recess m in which is placed a tninsverse bar m5 of similar form in cross section. and to the bottom of which is secured a plate m which is held in place by a transverse lock plate m7 secured to the carriage c by screws ma.

'The rear end of the rock beam m2 is provided with a fork-shaped head m thrugh which is passed a pin n. on which is rotatably mounted a block bearing n2, and mounted on the crank of the shaft d is a split bearingr is and two rods o are mounted in connecticut with Lne bearings n and u as shown.` The rods 0 are threadedat their upper and lower ends` and provided with nuts 02, and said rods aie provided above, the bearingn* with adjusting nuts o above which are placed llanged collars 0, and the bearing lf3 is provided with downwardli directed hubs n'and mounted on the rods and restinzcr on the flanged collars o* are strong spiral springs ,fa the tension of which may be adjusted by means of the nuts oi.

lu the use ot this machinix the workholder or holders having..r the usual electrodes are placed on the table o. as in the patent hereinbefore referred to` and said work holder or holllers and said electrodes may be of any preferred torni and ctnistruction. and the electrodes are preferably watercooled. and the parts to be riveted or connected are placed on said table and held b v said holder or holders as in the patent reterred to.

In this invention. however. the electrode support or holder` .7l which` in connei'tion with the plnngreitl-f. is carried by the head g3 of the electrode carrier and plunger guide f7 as in the patent referred to. is provided with a swiveled head z: which ntounted on a reduced extension Zz ot the part z and is held in connection `therewith b 'v transverse plate or bar la through which is passed a screw 71"'. and with thisiconstruetion the electrode 1' has a swiveled connection with the support of which the head 71,2 of said holder forms a part. and seid electrode a' may be freely turned on the support f1.

The electrode z' consists of a top pertg Tft and a bottom part. i". and the top part il is connected with the part h2 by screws or bolts e" which are insulated from the part i12. and said part Il? is insulated from the part il'. as clearly shown in Fig. 7.

The bottom part t" of the electrode t' is cylindrical in form and provided with a. spiral groove if inclosed by a sleeve 5" provided with ports or passages i and i". and the port or passage i communicates with the top member of the spiral groove vt"-. while the port or passage i conni'iunicates with the bottom member of said lQ'roove and water supply and disclmngel tubes or pipes 1' and i are connected with the sleeve 1 or the port-s or passages i and i therein, and by means of this construction the electrode i may be kept cool or pre-vented from overheating when in use.

The operative part of the electrode 1' consists of a plug r havingy a tapered shank rf which is driven into a corresponding` aperture in the. bottom part i? of the electrode. and the top part i of the electro-de. is extended at. one side and connected there with is a keeper s in which is secured a con ductor s* which. in practice, is commited in a transformer in the usual manner. or as shown and described in. the patent referred to.

The operation will be similar to that of the patent retorted to. and will be. readily understotal by those familiar with the op l. it)
